Reading these numbers
This gauge reports gage height, measured against a local reference point at the station rather than sea level. The number is useful for tracking rises and drops, but it is not an elevation, so do not compare it with charts that list elevations above sea level.
On a reservoir, a few feet of drop changes the shoreline more than you would think. Low water exposes stumps, sandbars and old roadbeds that are normally well under the hull, and some ramps end before the water does.
High water brings its own problems: floating debris after storms, flooded docks and courtesy piers, and no-wake rules near flooded campgrounds. A quick look at the trend before you hitch up saves a wasted trip.
The gauge is about 1 miles from the center of the lake and is listed by USGS as Lake Sumner near Fort Sumner, NM. Wind can pile water up at one end of a big lake for a few hours, so short spikes on a windy day are normal.
